19.Force 3N, 4N and 12N act at a point in mutually!perpendicular directions. The magnitude of theresultant force is:(1) 19 N(2) 13 N(3) 11 N(4) 5 N

Answer»

the magnitude of the resultant force is 19N

magnitude of resultant force= 3N+4N+12N=19N(all the magnitude of forces are added up because all are in positive and applied in the same direction)
